If the clutch is not able to meet the above requirements, it is considered a malfunction. After a fault occurs, first determine which phenomenon is the separation bearing damage. After the engine is started, the clutch pedal is lightly pressed. When the free travel is just eliminated, the “rusting sound” is the separation of the bearing.

When checking, the clutch bottom cover can be removed, and then a few accelerator pedals are pressed to slightly increase the engine speed. If the sound is louder, observe the presence or absence of Mars. If there is Mars, the clutch release bearing is damaged. If Mars is in a single strand, it means that the separation bearing balls are broken. If there is no Mars, but the metal breaks, it means excessive wear.
